I use mendeley to generate my bib file so I have a very large list of items (3000+) and since mendeley collects the bibliography information sometimes from the pdf file, there may be errors and strange characters. I guess this is why I get the following error

! Package inputenc Error: Unicode char \u8:∗ not set up for use with LaTeX.

What should I do? I use Pdftexify on WinEdt8. packages are up to date

    \usepackage[utf8]{inputenc}% For proper input encoding
    \usepackage[citestyle=authoryear,isbn=false,maxcitenames=3,maxbibnames=99,doi=false,url=true]{biblatex} % place in the document preamble

example of a bib item gone wrong:

author = {Biais, Bruno and Weill, Pierre-olivier},
file = {:D$\backslash$:/Gdrive/Drop/Dropbox/mendeley/Biais, Weill - 2009 - Liquidity shocks and order book dynamics ∗ - Unknown.pdf:pdf},
keywords = {bid-ask spread,limit-order book,liquidity,search},
pages = {1--51},
title = {{Liquidity shocks and order book dynamics ∗}},
year = {2009}

here I guess the * is bad...

  • Do you need all 3000 bibtex entries in this article? Can you limit the .bib file to some subset you actually cite?

  • well yes the idea is to have one large bibliography database that I can use with each different article. but I guess the problem here comes rather from the incoding... do you have an idea? many thanks for your help Aug 6 '13 at 13:46

    You should show us one or two of that entries which causes the problem ... You know a lot of your problem but you do not tell us the relevant things. So we can only guess ...

  • @Noobie My strategy with Mendeley is to have a folder (in Mendeley) for each article I write, and when I want to cite something I put it in that folder. Then you can select all in that folder and export a specific .bib file for each article. Its a bit more work, but it can save you much heartache when trying to sort out encoding issues because you'll have a much smaller subset of references to go through.

    @Noobie Write the name of the user preceeded by @ if you want to notify him... Anyway I get the same errors as you. Ulrike's suggestion doesn't work for me. Notice that the character you have is not an asterisk. Replacing with * I get no errors. Aug 6 '13 at 15:09

first, let me thank @karlkoeller @jon @Ulrike Fischer @darthbith and @Bart Arondson for their help.

What I did :

1) export a small bib file containing all the citations I need. nothing more 2) correct manually the mistakes generated by mendeley 3) contemplate a well compiled pdf

thank you all, I hope this can help other mendeley users
